Design of power communication terminal based on distribution network protection system

With the large-scale integration of distributed power sources, energy storage, and bidirectional charging stations into the distribution network, there is an urgent need for the joint optimization of distribution network protection services and communication technologies to achieve efficient fault isolation and rapid self-healing. In response to the new requirements for distribution network protection services, a hardware and software solution for an integrated distribution network protection communication device has been designed, and the communication performance of the device has been tested. The test results indicate that the device can meet the communication needs of distribution network protection services and can be applied in various scenarios of distribution network protection.
